What’s an El Niño and what does it mean for climate change?

El Niño, a weather event that opposes La Niña, occurs every few years, prompting questions about its connection to climate change.

According to Dr. Stefan Schnitzer, professor of biological sciences at Marquette University, climate change may exacerbate ‘normal’ El Niño effects, as reported by MarketWatch

This year’s El Nino is expected to be one of the strongest on record

Increased global temperatures will exacerbate El Niño events, particularly in areas with higher rainfall.

Global warming is produced by greenhouse gas emissions from burning coal, oil, and gas, which have accelerated historical climate shifts.

“Not only was last month the warmest August on record by quite a lot, it was the globe's 45th-consecutive August and the 534th successive month with temperatures above the 20th-century average,” said NOAA

“Global marine heat waves and El Niño are causing additional warming this year, but as long as emissions continue to cause background warming, we anticipate breaking more records in the future,” she stated.
